I'm researching historical representations of disability in media. On the Disability History Museum's website, I want to find out how many 'Advertisements' are available in the 'Library Collections' that are related to 'assistive technology'. What is the total number of results for this specific query, and what are the earliest and latest years for which these advertisements are available?
Navigate to 'https://disabilitymuseum.org/dhm/index.html'. Click on the 'library' link (ID 150). In the 'Search Collections' section, select 'Advertisement' from the 'Format' dropdown. In the 'Keywords' text input field (ID 150), enter 'assistive technology'. Click the 'submit' button (ID 164) to perform the search. Identify the total number of results for the search query. Determine the earliest and latest years of the available advertisements related to 'assistive technology' from the search results or the page context.
The agent successfully navigates to the 'Library: Overview' page. The agent correctly selects 'Advertisement' from the 'Format' dropdown. The agent correctly enters 'assistive technology' into the 'Keywords' field. The agent successfully submits the search query. The agent states the total number of results for 'Advertisements' related to 'assistive technology' (e.g., '14 results'). The agent identifies the earliest year for these advertisements as '1906'. The agent identifies the latest year for these advertisements as '1980'.
