Research Resources

In order to make library resources more accessible to members, we now offer fee-based library research services. An “S” at the end of any book or resource listing means that you can request that a CGSI volunteer search that particular resource for a specified name, place, or defined piece of information. See our CGSI Library Research Policy for cost.

We still provide, at NO CHARGE for members, help on deciphering town names in documents, locating town or villages, providing postal codes, and advising on correspondence to the Czechoslovak region.

Requests should be sent to CGSI , P.O. Box 16225, St. Paul, MN 55116. Please include a stamped, self-addressed envelope along with your request.


The MGS Library Collection is housed in the Minnesota Genealogical Society (MGS) library. The MGS library is organized into the following groupings:

Foreign – Each ethnic group has their ethnic specific book holdings on separate shelves with call numbers that identify the group; for example, all CGSI books in the “Foreign” group have a call number beginning with Frgn Cze.

State – All holdings in this category are grouped by state; call numbers for books in this category begin with US, with the second entry designating the state; for example, the call number for all books in the Wisconsin section would begin with US WI, for Nebraska with US NE, etc. CGSI’s holdings for a specific state are included on the respective state shelf along with those owned by other groups.

Family History – All books in the “Family History” category are also grouped together in the library. Call numbers for this category begin with FH. CGSI’s family histories are included in this grouping.

Maps – Each ethnic group has their specific map holdings in separate map cabinets. The call numbers for CGSI’s maps begin with Map Cze.
