Archives vs. Mould: Facts on Fungus

Have you ever opened your fridge to discover something green and fuzzy inside? Or opened an old book and been hit with a strong musty odour? Chances are you have come into contact with mould.

Mould spores occur naturally outdoors and you come into contact with them every day. But in an archival setting indoors, it’s a much different story. Problems begin when the spores come into contact with collection material in an environment that nurtures their growth. Besides the physical damage that mould brings to the material, mould can also affect your health. With this in mind, there are certain precautions you need to take when handling contaminated material.

Fortunately, most of the mould that we come across in the holdings of Library and Archives Canada (LAC) is dormant. This means the spores are in a state of hibernation because the humidity level and temperature are carefully controlled. Ensuring that the environment is not favourable for mould activation and growth is one of the main factors we consider when storing collection material.

All treatment work is done in a biological containment hood after freezing the contaminated material for 48 hours at -35^(0) Celsius to ensure that the mould is inactive before cleaning. Because mould contains pigments that can cause staining, treated material often does not look any different than untreated material. For this reason, material that has been cleaned is clearly identified with a “Treated for Mould Contamination” label.

However if, during a visit at LAC, you suspect that the collection material you are handling is contaminated by mould, the rule of thumb is that it is best not to disturb mould. Therefore, you must immediately stop handling the contaminated documents! Then:

Report the problem to staff immediately; and

  • Leave it to the staff who will take the appropriate actions such as segregating and sealing the material in a plastic bag to ensure that the mould does not spread.

The most important thing to remember is to protect yourself. The following is a list of protective equipment you can use when handling personal documents affected by mould:

  • gloves (Nitrile™ or latex);
  • mask respirators (specially designed and fitted to filter out spores);
  • lab coats;
  • goggles.

As long as you use common sense and take the necessary precautions when dealing with contaminated material, you should be fine, and with any luck, most of the mould you encounter will be limited to the inside of your fridge.

The Working Process of Arnaud Maggs

Did you know that the Arnaud Maggs: Identification exhibition, which is currently taking place at the National Gallery of Canada, includes several items from Library and Archives Canada’s (LAC) collection? Our materials in this exhibition are used to emphasize the artist’s working process and strategies.

In fact, Library and Archives Canada holds the Arnaud Maggs fonds, which follows Maggs’s professional career, from his time as a prize-winning graphic designer and commercial and fashion photographer to his later work exploring portraiture. In addition to finding examples of the artist’s drawings, prints, paintings, watercolours and photographs, LAC‘s archival source materials allow you to discover his artistic process, including such items as the artist’s notebooks and contact sheets from which he selected the best portraits.

Arnaud Maggs, one of Canada’s foremost photographers and artists, was born in Montréal in 1926. He was awarded the Scotiabank Photography Award in 2012, one of Canada’s most prestigious photography prizes.

The exhibition runs until September 16, 2012.

Faces of 1812: Virtual Exhibition

Faces of 1812 presents some of the men and women, both combatants and civilians, who experienced the War of 1812.

The War of 1812 united French-speaking and English-speaking Canadians, First Peoples, and the British against a common foe. The victory gained through their successful joint defence helped lay the foundations for modern Canada.

This virtual exhibition highlights some of the rare portraits and archival documents presented in the exhibition Faces of 1812 on display at the Canadian War Museum, in conjunction with the Museum’s own major exhibition, 1812. Both exhibitions will be shown from June 13, 2012 to January 6, 2013. This virtual exhibition also includes additional works that highlight the War of 1812 as a rich and continuing source of artistic inspiration, commemoration, and reflection.

Discover the Access Codes for Archival Records at Library and Archives Canada – Part II

In our post “Discover the Access Codes for Archival Records“, we reviewed four of the most common access codes 90, 32, 10, and 18. However, there are other access codes that you may encounter while undertaking your research. They include access codes 96 and 99.

  • Restrictions vary (Code 96)

Access code 96 indicates that within a group of records there exists more than one type of access condition. For example, since the Department of Transportation fonds (RG12) contains records that are open (code 90) and others that are restricted (code 32), the fonds-level access condition are indicated by “restrictions vary” (code 96).

Access code 96 can be applied to more than just fonds-level descriptions. It can also be linked to series, sub-series and accessions. However, it does not apply to individual volumes and files.

Remember:

Access code 96 usually means that there are more specific descriptions available for the records you are researching. In some cases, these records can be accessed by simply clicking on the “lower level descriptions” link in the “Fonds consists of” section of a record description.

In other cases it will be necessary to consult a printed finding aid. To learn more, read our post Discover Finding Aids.

  • To be determined / closed pending processing (Code 99)

Access code 99 means that the access conditions for a group of records have yet to be determined. Usually this is because the records are being processed. In the following example, while the photographic material is open, the access conditions for the textual records have yet to be determined:

  • Open, no copying (Code 95)

Access code 95 indicates that the records are open and can be consulted, however, at the request of the donor, the records cannot be copied or reproduced.
