Start academic research collection
Predefine the question and sample
Choose official APIs or approved datasets first. Record the population of interest, source list, sampling procedure, fields, ethics review and exclusion rules before collection.
Run a controlled pilot
Verify one exit per requested market and hold URL, browser language, account state and collection window constant. Save response state, timestamp, parser version and route evidence without proxy secrets.
Freeze the methods and manifest
Review missingness and extraction quality, version the source manifest, and export only the approved dataset. Preserve exclusions and failed observations alongside the accepted records.
Missing observations belong in the methods
A fictional study samples the same approved pages in two markets and keeps unavailable records in the sample log.
Report collected, excluded, refused and missing observations against the original sampling frame. A regional proxy sample does not establish population representativeness; describe the scope and controls of the actual observations.
What to measure: coverage of the declared sample
Report collected, excluded, refused and missing observations against the original sampling frame. A regional proxy sample does not establish population representativeness; describe the scope and controls of the actual observations.
Use an API or research dataset first
For scholarly metadata, OpenAlex documents its research index, data access and REST API. Check an official dataset, repository export or publisher agreement before building a page collector. A proxy adds value when the approved study specifically needs a regional network observation.
Define the research question and sampling frame before choosing locations. Separate a comparison of network delivery from a study of local people, behavior or opinion. A proxy exit supplies one network viewpoint and does not make the collected sample representative of residents.
Keep methods reproducible
Record requested and observed country, source URL, UTC time, request method, response class, language, account state, client and parser version. Preserve the sampling seed and URL manifest when your study uses random selection. Use hashes or controlled identifiers where raw content should not be retained.
Hold non-network inputs constant across markets, or vary them in explicitly separate conditions. Record refusals and missing pages in the original sample rather than silently replacing them. A repeated capture can reveal temporal variation that would otherwise be attributed to geography.
Pilot the byte and review budget
Start with Residential Flex for country-level samples. Choose Premium Residential when a supported finer selector is part of the method. The regional QA guide provides a controlled comparison worksheet.
Illustrative sizing: 100 approved pages in five market conditions, averaging 200,000 response bytes, produce 0.1 GB of response payload. Include repeats, failures and overhead in the pilot log and compare account usage before sizing the full run. Budget human review alongside bandwidth.
Follow the study’s access and ethics boundaries
Use the institution’s ethics and data-management review where required. Obtain the source permissions and reuse rights appropriate to the actual project. Follow robots instructions and source rate limits, and stop on authentication walls, challenges or explicit refusals.
Minimize personal and sensitive information, set access and retention controls, and document correction or withdrawal handling. Do not use rotating identities to enlarge a source quota or bypass controls. The resulting methods statement should describe what was observed and excluded without claiming broader coverage than the study supports.
When the result looks wrong
The observed country differs
Confirm the generated country selector and inspect a fresh connection with the IP diagnostic.
Next step: Keep the mismatch in the record and correct the route before the sample.
A response is incomplete
Compare the content type, required fields and source template with the extraction contract.
Next step: Quarantine the response and review the parser before adding it to the accepted dataset.
The source returns a refusal or rate limit
Inspect the response class and the source-wide request budget.
Next step: Pause the queue, honor Retry-After and resolve the access or budget issue before continuing.
