It is sometimes possible to access additional databases and other electronic resources via public libraries and, occasionally, other academic libraries.
In the United States, public library access is typically available to state residents and requires registration in the form of a library card. You can google the name of your state with the term public libraries to find libraries, and then visit their web sites to find out how to apply for a library card. Often, public libraries offer an e-card, for which you can apply online and get instant remote access to some or all of the library databases. In Ohio, the State Library of Ohio provides a list of all public libraries; this may also be the case in other states.
Prior to the pandemic in 2020, many academic libraries offered walk-in visitors access to some or all of their databases. This practice is now far less common, but you can check university library web sites to find out if they allow visitor access. Due to licensing restrictions, very few academic libraries are able to provide remote access to databases and other electronic resources by persons not currently affiliated with their institutions, including alumni.
Trade and other professional organizations can be sources of valuable information about an industry. Often, though, this information is available only to organization members, so be sure to find out if clients are members of any such organizations or associations. IBISWorld reports and Standard & Poor's Industry Surveys, available in the NetAdvantage product, list trade associations; you can also google the name of an industry with the terms "association organization site:.org" to find names.
