A good place to start is the Screen Arts and Cultures Research Guide. This is certainly not an exhaustive selection of the resources available at UM, but it’s a nice selection of materials particularly useful for research in our field and provides a good organization of what resources to use depending on what kind of materials you’re hoping to find (retrospective, general, popular press vs. academic, etc).
For books, of course, use the Mirlyn catalogue to find out what is available at the UM libraries. Much of what you’ll be looking for will be available at Shapiro or Hatcher, but I would recommend not limiting your search to just these, as there are often useful resources in the many specialty libraries on campus. When searching for books, a simple but important thing to keep in mind is that you should try a number of different keyword searches. For instance, if a search for “1930s Film” does not yield many relevant hits, try “1930s Cinema” or “1930s Hollywood” or “Classical Hollywood,” etc. Each one of these searches will likely yield a number of different sources, improving your chances of finding those which will be most useful to you.
Be creative and don’t limit your search to just your film title or era. A search for books on your film’s genre (“melodrama,” “film noir,” “musicals,” etc) may lead you to in-depth analyses of your particular film you might not have found otherwise or can offer you a useful cinematic/historical context in which to place your film. Similarly, searches on your film’s director, producers, even stars may lead you to materials that cover your film. If you start your search with Wikipedia or IMDB, pay attention to important names or topics in these write-ups and add those to your list of research terms. You want to spread your net as wide as possible to begin with and then to worry about cutting down from there. Keep this same idea in mind when researching your era/region/historical period and so on. In some cases, historical era and such will be addressed in discussions of films from the period, but they may not be written about adequately for your purposes and you will likely need to search for non-film-related history sources as well.
This keyword/search term strategy should also be applied to searches for academic articles. Part of your research should be based on academic, “peer-reviewed” articles. These are also called “refereed” articles. What this means, basically, is that these are articles that have been reviewed and fact-checked by a panel of experts prior to publication. These will mostly be found in academic journals, not popular press. The Screen Arts research page linked above includes a number 0f databases for finding these articles through the UM library, such as Academic One File or MLA. There are also links to film-specific academic search engines, such as FIAF or the Film and Literature Index. A number of additional search databases are available on the library website and different databases will often contain different materials. It is important to keep in mind that, while some of these databases will provide you with a pdf of the specific article on the spot, many of them will not. Instead you will have to write down the citation and see if that journal and specific issue are available at the UM library, whether in hard copy or on microfilm/microfiche. If it is, you will need to physically go to the library to retrieve it. Plan ahead for this and make sure that you leave yourself enough time.
You also may be working from popular press sources. Note that these will not count as “peer-reviewed” sources. Examples of popular press journals would be Variety, The New York Times, Life Magazine and others that the public at large would be able to purchase a copy of on a newstand. These can be useful for your research, but most likely if you are using these sources they should be part of your historical research. This means that if you want to use an article about The Wizard of Oz from Variety, you should use one from 1939, not one from 2009. You will use this article to support your claims about how this film was received in the popular press or by the public during the time of its release. An article on the film from Variety in 2009 will not be able to give you this same information.
To find film reviews from the period in which your film was released, some of your best sources will be the historical newspapers available on Proquest Historical. This database is linked on the Screen Arts Research Guide under the “retrospective articles” section. On this search engine you will be able to choose a number of newspapers (or individual newspapers) and a time range to search. Again, be flexible about your keywords and search terms. You may have to play with a few different things but you should be able to find at least a review or two (most likely a lot more) of these films. If you are getting too many irrelevant resources, narrow your search by putting your film title into quotes. “The Wizard of Oz” rather than wizard of oz. Additional popular journals/magazines/newspapers can be found in bound copies at the library or on micofilm/microfiche. A good resource for searching out specific citations within these sources is the Reader’s Guide Retrospective database. You can find this linked under the same “retrospective” tab on the Screen Arts Research page as the Proquest Historical database.
Microfilm/microfiche may be another useful resource in your research. As mentioned above, many popular press sources from your time period are only available on microfilm. Additionally, if you are interested in researching industry periodicals or exhibitors’ trade journals (if you are interested in seeing how the film was talked about by/sold to people who worked in the film or movie theater industry), most of these sources are on microfilm. A listing of relevant materials and their microfilm call numbers can be found on the Screen Arts Research Guide under the “industry periodicals” tab. Microfilm and microfilm readers are located in the space between Hatcher and Shapiro. If you enter Hatcher library and go to the second floor and head toward the connector to the third floor of Shapiro library, you will pass through the microfilm area. There are library assistants at the desk who should be able to assist you in setting up the film on the reader, printing from the film, etc. Please keep in mind that some of the readers will require a copy card to print from the film (I believe the cost is 25 cents a page). Also keep in mind that working with microfilm can require some extra time for scrolling through the reels to find the section you’re interested in, as well as time to set up the film and to wind the film back onto the wheel after you are finished.
I hope this is helpful to you in your research. I look forward to reading all of your projects and seeing what you come up with. Happy hunting!
