My advisor says narrow my thesis topic but the online library catalog returns zero relevant sources, what steps can I take?

It sounds like you’re hitting the classic wall where academic rigor meets the reality of search limitations, but the fix is usually to broaden your search parameters while keeping your thesis argument tight. When you get zero results, it’s rarely because your topic is too niche for the world; it’s usually because you’re using search terms that are too restrictive or you’re looking for a direct match rather than a conceptual one. You don't need to find a source that perfectly mirrors your exact argument. Instead, look for "building block" sources that cover the individual components of your thesis. If your topic is the impact of specific remote-work software on the mental health of freelance graphic designers in rural areas, you won't find that exact paper. However, you will find plenty of literature on remote-work communication, the psychological effects of isolation, and the gig economy. By synthesizing these separate fields, you’re actually writing a more original and scholarly paper than if you had just found a pre-packaged study that did the work for you. The biggest misconception here is that a literature review must only contain sources that are identical to your thesis. In reality, your job is to act as a bridge between existing conversations. If you’re struggling with paywalls, remember that you should only be using your university’s proxy links or VPN access to reach those databases; if you’re searching via a general web engine, you’ll constantly hit those barriers. Reach out to your library’s research desk immediately, as they can often pull articles through interlibrary loan or point you toward hidden digital collections you might have missed. Don't be afraid to adjust your thesis slightly if you find a cluster of high-quality, peer-reviewed articles on a related sub-topic. It’s perfectly acceptable to pivot your focus toward where the evidence actually exists rather than forcing a narrative where the data is thin. Finally, consider that the "narrowness" your advisor wants is likely about depth of analysis rather than a lack of source material. You can have a very specific argument while drawing from a wider range of foundational texts. If you’re still stuck, try mapping out the key concepts of your thesis and searching for each one independently to see where they overlap. You might find that your thesis is actually a unique intersection of two well-researched fields. Take a breath and focus on finding the best available research on the pillars of your argument, then use your own voice to connect those dots in a way that feels fresh and academically sound. You have enough time to pivot your search strategy if you start looking for thematic connections rather than exact title matches today.
