Books in the Walter Geology Library are shelved in the stacks by Library of Congress (LC) call numbers. The Library of Congress call number system is alpha-numeric and allows for classification by subject. Example of an LC call number: QE 75 G756.
New journals are held in the Periodicals Reading Room, shelved in alphabetical order by title. Journals are kept as loose issues in the Reading Room until the library receives a complete volume, and then the loose issues are sent for binding. Binding normally takes two or three months, after which the bound volumes are shelved by call number in the stacks.
Books with a library catalog location of Geology Library Oversize are located in the Oversize/Folio area of the Library. Oversize materials also have a designation of a -Q- or -F- (or -L-) before the start of the Library of Congress call number, e.g. -Q- QE 75 G469 or -F- QE 75 G469.
Due to limited space, not all books with -Q- or -F- designators are in the Oversize/Folio section and may be found in the regular stacks.
How do I find what I need?
In the Oversize/Folio area, there are three divisions of materials and you may have to search all three sections:
1) Items that are small enough to stand upright
2) Materials that are so large they can only fit one on top of each other
3) Materials that are small enough to sit side by side
Microfiche are located in two filing cabinets along our north wall.
What can I find here?
The most important microfiche holdings in the Walter Geology Library are the United States Geological Survey (USGS) Open File Reports. These USGS Open File Reports are almost complete from 1981 to the present. The USGS Open File Reports on microfiche are not individually listed in the online catalog. To access them you must first find the sequential number assigned it by the USGS. Our United States Geological Survey (USGS) Publication Guide (link to this), GeoRef and other bibliographic sources can help with this.
How can I view a microfiche?
A microfiche viewer is located in a study carrel next to the microfiche filing cabinets. The microfiche reader does not have printing capabilities, but microfiche are available for check-out. The PCL has a microfiche/film reader that prints and that can scan to a Flash drive.
The Geology Library's microfilm holdings have been moved permanently to PCL. They include a large number of Theses and Dissertations completed at other universities on the subject of Texas geology. Ask for assistance in the Periodicals and Microforms area of PCL.
Off Site Materials
Some Walter Geology Library materials are stored off-site in the Library Storage Facility (LSF), at the Pickle Research Center. You may request these materials, and it may take anywhere from 3 to 5 business days after the request for the items to arrive.
There are no items with Dewey Decimal call numbers housed in the Walter Geology Library. Any Geology Library items with Dewey Decimal call numbers will have a Library Storage location. Dewey call numbers start with a numeral, distinguishing them from Library of Congress call numbers which start with a letter of the alphabet. Dewey Decimals look something like this: 557.694 D284g. We no longer have active subscriptions to most journals with Dewey call numbers.
