The different OER referatories and repositories aren't built the same, don't have the same submission processes, and don't have the same items, so it is good to have an idea of what makes each unique before you start spending your valuable time searching without a strategy that takes into account the tools at your disposal.
The comparison below is only meant to be an instructive exercise, and only covers a few of the most popular OER search tools.

As you can see, there are significant differences between the search tools, and which tool you use will depend on the information you've gathered during the consultation. Practicing on the OER search tools will increase your knowledge and instincts.
Search tools, especially the metasearch tools, allow you to cover a lot of ground in not much time. It isn't the only way to locate relevant OER, though. Your communities, whether that be a community of subject matter experts or a community of academic support staff or something else, are a great source for OER.
OER adoption registries: some organizations are keeping track of and publishing lists of OER that have been adopted, and the courses they've been adopted for. For example:
OER and SME listservs or forums: This is a good option if you have looked but can't find anything, not as the first step every time you need to find an OER. Sometimes your colleagues will have "been there, done that" and can suggest some excellent resources.
Faculty Learning Communities (FLCs): These groups often have subject matter experts, instructional designers, and librarians, and they can exist both within institutions or across academic consortia.
OER Advocacy Networks: These networks have various group meetings where you can bring your question to people who love to help. Examples are the Open Education Network (OEN) and the Global OER Graduate Network (GO-GN).
Do you have anything that you've created that could be expanded into OER or an open textbook? Sometimes existing content is the best place to start.
