Title: GSscraper and greylitsearcher - useful but flawed tools for searching for studies in evidence syntheses
Abstract: Web scraping is a useful technique for extracting patterned data when searching for studies in evidence syntheses. It holds promise where search results cannot be exported directly in bulk, and allows data to be integrated into eligibility screening pipelines. Here, I report on two tools (GSscraper and greylitsearcher) build using basic web scraping in R and hosted as Shiny apps. I explain the problems associated with these methods and call for additional support in helping to make these web scraping tools resilient to code fluctuations in the underlying websites (Google and Google Scholar).
