Vocational Activities

Requirements

1. Define:
   • Preservation
   • Conservation
   • Restoration
   • Interview someone responsible for the restoration and conservation area of a library and report, in at least 100 words, what they highlighted about the work of a restorer and conservator.
   • Cultural Heritage
   • Tangible assets
   • Intangible assets
   • Movable assets
   • Immovable assets

   Answer: 1) Preservation: the set of actions that prevent deterioration and prolong the life of an item, controlling the environment (humidity, light, temperature, handling and storage) — it acts before the damage happens. 2) Conservation: direct interventions that stabilize and repair existing damage, maintaining the originality of the item as much as possible (e.g.: cleaning, small repairs, combating fungi and insects). 3) Restoration: a deeper intervention that recovers the integrity of a damaged item, replacing lost parts with technical criteria, documentation and reversibility, without altering the character of the original. 4) Interview with a person responsible for the restoration and conservation of a library: when talking with the person in charge, they emphasized that the craft requires a lot of patience, ethics and respect for the history of the document. They explained that each piece is unique and that the professional must intervene as little as possible, always in a reversible and documented way, so that future generations can re-evaluate the work. They spoke of the importance of controlling the environment (temperature, humidity and lighting), of using suitable materials and products and of combating fungi, insects and the acidity of paper. They stressed that the work is silent and meticulous, requires knowledge of chemistry, history and manual techniques, and has the mission of preserving the memory and culture recorded in documents. 5) Cultural Heritage: the set of goods of historical, artistic, cultural or scientific value that represent the identity and memory of a people, which must be protected and passed on to the next generations. 6) Tangible goods: material and physical goods that can be touched, such as documents, books, buildings, works of art and objects. 7) Intangible goods: immaterial goods, linked to knowledge and culture, such as festivals, music, dances, legends, recipes and traditions. 8) Movable goods: those that can be transported or moved, such as books, paintings, furniture, sculptures and documents. 9) Immovable goods: the fixed ones, attached to the ground, such as buildings, churches, monuments and historic sites. — Distinguishing preserving, conserving and restoring — and the types of heritage — is the foundation of the work of those who care for memory and culture.

2. Define the following terms:
   • Heritage listing
   • Heritage

   Answer: 1) Heritage listing (tombamento): the official act by which the public authorities (federal, state or municipal) recognize the historical, cultural, artistic or documentary value of an item and register it in a Heritage Register (Livro do Tombo), thereby protecting it legally. A listed document or collection cannot be destroyed, altered or exported without authorization, and its owner is obliged to conserve it properly. In Brazil this instrument is coordinated by IPHAN. 2) Heritage: the set of goods with recognized value for a person, an institution or for all of society. In the field of document conservation, one speaks of cultural and documentary heritage: the documents, books, records and archives that hold the memory of a people, a church or a family and which, for this reason, deserve to be preserved and passed on to the next generations. — Binding: paperback, hardcover, spiral. Spine with title. Text block sewn or glued. Cover: card, leather, cloth. Restoration intervenes in damage. Conservation prevents it. Foxing: fungi or metallic oxidation create stains. Acidification: acid paper (from 1850 on) deteriorates. Reinforcement: Japanese paper or tyvek. Hand sewing for old books. Acid-free materials preserve for centuries. Adventism: respect for cultural heritage.

3. Know at least 1 school of book and document restoration.

   Answer: Brazil: Courses at the National Archive (RJ), USP, Unicamp, IBRAM (Brazilian Institute of Museums). International: West Dean College (United Kingdom), Camberwell College (London), American Academy of Bookbinding (USA), L'École Estienne (France). The courses cover binding, restoration, preventive conservation and the treatment of damage. — A regulated profession requires technical training. Courses: bachelor's degree, specialization, postgraduate study. Content: paper chemistry, biology (fungi, insects), traditional techniques (sewing, gilding) and modern ones (Japanese paper, tyvek). Internships in museums and libraries. Job market: National Library, historical archives, museums, private studios. Adventism: investing in technical knowledge to preserve valuable cultural heritage.

4. What are the basic criteria for considering a book or document rare and of value?

   Answer: Age (usually >100 years), rarity (few known copies), historical/cultural importance, relevant authorship, limited edition (1st edition, autographed), unique content (manuscript, original illustrations), state of conservation, the presence of an ex-libris or marks of provenance, and demand in the bibliophile market. — Age is the initial factor. Rarity: research in catalogs (WorldCat, Estante Virtual). Importance: scientific, literary, religious milestones. Autographed or with a special dedication. A 1st edition is more valuable than reprints. Manuscripts are unique by definition. Conservation affects the price (10-50% difference). Provenance: ownership by illustrious figures increases value. Market: auctions (Christie's, Sotheby's), specialized booksellers.

5. Write a summary about care in the conservation of books and documents, taking into account the following items:
   • Cleaning
   • Storage
   • Personal protective equipment
   • Equipment
   • Different types of material in documents or books
   • Climate control
   • Ultraviolet rays
   • What a "pied" (jumbled/disordered) book is and how to treat it

   Answer: 1) Cleaning: careful cleaning to remove dust, dirt, dead insects and residues, always dry, with a soft-bristle brush, brushes and a low-power vacuum with a protective screen. You work from the center to the edges; never use water, adhesive tape or common cleaning products, which accelerate deterioration. 2) Shelving: books should be kept upright, aligned by the spine, with support (bookends) so they do not topple over; large or fragile volumes are laid flat. Do not cram copies on the shelf and keep them away from the walls to allow ventilation. Loose documents go in folders and boxes of neutral (acid-free) paper. 3) Personal protective equipment: wear cotton or nitrile gloves, a mask and, when there is mold or a lot of dust, an apron and goggles. This protects the operator from fungi and mites and protects the document from the grease, sweat and acidity of the hands. 4) Equipment: a soft brush and brushes, a vacuum with a filter and power adjustment, spatulas, padded weights, a clean and lit table, boxes and folders of neutral paper, a thermo-hygrometer to measure temperature and humidity and, ideally, a fume hood or ventilated area for cases with fungi. 5) Different types of material of the documents or books: each support requires its own care. Acid paper (newspaper, old common paper) yellows and breaks easily; parchment and leather dry out and need stable humidity; photographs and films are sensitive to light and heat; stamps and inks can fade. Knowing the material avoids wrong techniques. 6) Climate control: the ideal environment keeps the temperature around 18 to 22 °C and the relative humidity at 45 to 55%, stable, without sudden variations. Heat and high humidity favor fungi and insects; very dry air dries out and breaks the paper. Air circulation and control with devices are recommended when possible. 7) Ultraviolet rays: ultraviolet radiation (direct sunlight and fluorescent lamps) fades inks, yellows and weakens paper irreversibly. For this reason, direct light is avoided, curtains, UV filters on windows and lamps are used, and lighting is kept low in storage areas. 8) A pasted/stuck book and how to treat it: a pasted book is one whose pages have become glued/stuck to each other (due to humidity, mold, spilled glue or the action of time), forming a hardened block. The treatment must be slow and done by experienced hands: the environment's humidity is controlled and, very carefully, controlled humidification and thin spatulas are used to separate the pages one by one, drying between absorbent papers under light pressure. Severe cases should go to a professional restorer, since forcing the pages tears them. — Controlled temperature and humidity prevent foxing, mold and drying out of paper. UV sunlight degrades cellulose and ink. Greasy hands stain; cotton or nitrile gloves. Shelves 5 cm from the wall for circulation. Tilting a book ruins the spine. Pests: cedar repels, periodic pest control. Acid-free boxes for documents. Digitization: a professional scanner. Adventism: responsible cultural and heritage care.

6. How do you preserve old newspapers or maps?

   Answer: Handle with gloves. Place between sheets of acid-free (non-acid) paper in a PVC-free polyester plastic folder. Keep in a dry, dark place, with a stable temperature (18-22°C) and controlled humidity (45-55%). Avoid folding; store flat. For consultation, digitize to reduce handling of the original. — Newspapers are more acidic than books (newsprint degrades quickly). Encapsulation in polyester (Mylar) protects without gluing. Suspended folders in a file. Large maps in a map cabinet (shallow drawer). Avoid PVC (it releases chlorine, attacks paper). Cotton gloves. Digitization on an A0 scanner for maps. Preventive conservation is more efficient than corrective restoration. Adventism: preserving cultural memory.

7. What are Fumigation Chambers?

   Answer: A fumigation chamber is an enclosed environment for decontaminating books and documents against fungi, insects and microorganisms. Methods: gas (phosphine), freezing (-30°C), modified atmosphere (anoxia with nitrogen) or gamma irradiation. — Industrial chambers used in museums and archives. Methyl bromide was banned for damaging the ozone layer (Montreal Protocol). Phosphine is more used today. Freezing eliminates insects (pupae, larvae, eggs). Anoxia: nitrogen replaces oxygen, kills aerobes. Gamma irradiation for extreme cases. Before treating a collection: identify the contamination, choose a method that does not damage the paper/ink. Adventism: preserving heritage.

8. What is Boric Acid and how do you use it?

   Answer: Boric acid is a chemical compound (H3BO3) used as a natural insecticide against moths, borers and cockroaches in collections. Application: white powder in cracks, behind shelves, in sachets on the floor. It can be mixed with flour or sugar as bait for ants. Non-toxic to humans in small amounts, but avoid contact with the eyes and ingestion. — A traditional insecticide, effective against cockroaches and moths. It kills by dehydration (affecting the exoskeleton) and ingestion (rupturing the digestive system). Advantage: it does not evaporate like aerosols. Sachets: cloth with powder. Caution: away from children and pets. In archives: it complements fumigation chambers. Alternatives: diatomaceous earth, essential oils (clove, eucalyptus). Integrated pest management is the recommended modern approach.

9. How do you treat a book that has been soaked with water?

   Answer: Act quickly (24-48h). Drain the water with the book standing, spine down. Place absorbent paper between pages (every 20-30 sheets), changing it frequently. Dry with a fan in a well-aired environment, avoiding direct sun. For a large collection, freezing and freeze-drying. Once dry, press to reduce deformations. — Time is critical: mold appears in 48h on damp paper. Do not use a dryer (heat stiffens). Change the absorbent paper every hour initially. Cross ventilation speeds it up. The sun degrades and curls. Freezing (-20°C) halts deterioration until freeze-drying. Freeze-drying: vacuum + cold extracts water without passing through a liquid state. Pressing between boards with weight after drying. Severe case: a professional restorer.

10. What is freeze-drying (lyophilization)?

    Answer: Freeze-drying is a drying process by sublimation: ice (frozen water) passes directly into vapor under vacuum, without passing through a liquid state. In soaked books, freezing at -20°C and then applying a vacuum extracts the water without deforming the pages, avoiding gluing, mold and rippling. A technique used in archives and museums. — Principle: the triple point of water (low P and T, sublimes directly). Equipment: an industrial freeze-dryer, a vacuum chamber. Process: 1) rapid freezing; 2) vacuum applied; 3) slow sublimation; 4) secondary drying at low temperature. Advantage: the paper comes back dry and flat. Applications: books after a flood, archaeological manuscripts. Cost: high, usually in specialized centers (National Library, partner institutions).

11. What is a hygrothermograph?

    Answer: A hygrothermograph is a device that simultaneously measures and records the temperature and relative humidity of the air over time. It is essential for monitoring environmental conditions in historical archives, museums, and libraries. — The hygrothermograph is a recording instrument that combines a thermograph and a hygrograph, measuring and recording the temperature and relative humidity of the air continuously on a drum with graph paper (or, in current models, in digital memory). It arose from the improvement of recording instruments in the 19th century (notably those made by the Richard brothers in France). Modern digital models (such as Vaisala and Testo) store the data in internal memory for analysis. It is a basic environmental monitoring device in archives, museums, and libraries.

12. What do you do with folded and dried-out documents and pages?

    Answer: You gently humidify in a humid chamber with water and cotton, apply uniform weight between absorbent sheets, and let it dry under a flat sheet of glass. Extreme cases: use controlled steam or consult a professional restorer. — Document unfolding techniques follow the protocols of the AICCM (Australian Institute for Conservation of Cultural Material) since 1976, being an international standard recognized by Brazilian and foreign professional archivists in use today.

13. Why can cardboard be more appropriate than plastic for the preservation of books?

    Answer: Acid-free cardboard allows air circulation, preventing fungus, maintains a stable neutral pH, and does not emit gases. Plastic traps moisture, releases plasticizers over time, and sticks to the pages. — Research by the Image Permanence Institute (Rochester, USA) proved that plastic polymers such as PVC release hydrochloric acid as they age, damaging documents. Neutral cardboard with a pH of 7-8 is currently considered the international standard for conservation.

14. With the help of your parents or guardians, find a document more than 50 years old and restore it, if appropriate, and store it in a proper way. (Example: certificates, newspaper pages, cooking recipes, letters or magazines, etc.).

    Answer: Clean it with a soft brush without water, repair tears with Japanese tissue and Kollagen glue, laminate it with mylar, store it in a neutral folder horizontally. Document the process with before/after photos. — Amateur document restoration is guided by IPHAN, with official booklets available online. Simple repairs (tears, folds) can be done at home, but heavily damaged documents currently require a professional certified in conservation.

15. With the help of your parents or guardians, find a book more than 50 years old, restore it, if appropriate, and store it in a proper way.

    Answer: You inspect the book, clean it with a soft brush, repair loose pages with neutral PVA glue, reinforce the binding if necessary, wrap it in a neutral cardboard cover, and store it vertically on a dry shelf, away from direct sunlight and moisture. — The restoration of old books requires patience and specific materials. USP offers free online courses on conservation, with basic knowledge currently being accessible for amateurs to make simple repairs to old family books in use.

16. Go to a library and help the librarian in the restoration of a material indicated and supervised by them.

    Answer: Schedule a visit, dress appropriately, and listen carefully to the instructions. Assist with tasks such as surface cleaning with a brush, organizing record cards, labeling, identifying damaged books, careful transport. Learn by observing and asking. Document the experience with photos and notes to present to the instructor. — Public and university libraries accept supervised volunteering. Safe tasks for a beginner: cleaning, organizing, assisting. Technical restoration is left to a professional. Use gloves and a lab coat if provided. Pay attention to specific guidelines. Each rare book has its own protocol. A quiet and respectful environment. One learns by observing professional methodology. Adventism: community service values time and talents.
