I need help gathering quantitative data from a set of pre-selected sources. I already have the entire list prepared, organised in an academic-research style bibliography, so you will not be hunting for new URLs—just pulling the numbers that matter. Most of the sources are online journals, research databases and a few dedicated websites. Here is what I am after: • Extract the specified numerical indicators from each source (I will provide a template that shows exactly which metrics to capture). • Log every value in a clean, well-structured spreadsheet (CSV or XLSX is fine), keeping one row per source and including a reference back to the original page or PDF for verification. • Note any missing or unavailable figures so I can follow up with the publisher if needed. Accuracy is essential. I will spot-check random entries against the originals before signing off. If you are used to tools like Python/pandas, R, or even a solid manual workflow with Google Sheets, that works for me—just make sure the final sheet is tidy, consistent, and fully traceable. Turnaround: please let me know how quickly you can work through roughly 150 sources, and feel free to flag any questions about formatting or edge cases as soon as they arise.
