3. Poll Structure
Each poll consists of a statement; you vote on whether you support the statement. All polls will be 5-way polls; you’ll vote either "strongly favor", "weakly favor", "neutral", "weakly against", or "strongly against".
Polls phrased as "Return X" indicate that the paper was sent to Library Working Group in the past, and Libary Working Group returned it to us with questions. Polls phrased as "Send X" indicate that the paper has not previously been sent to Library Working Group.
All committee members may vote, but if you have not participated in the Library Evolution discussions of a poll (in-person, over telecon, or over email), please consider whether you sufficiently understand the topic to be able to vote in an informed manner. If you do not, please choose to not participate in the poll.
If you do not want to participate in a poll, select the "I do not want to participate in this poll" option. Those who do not participate in a poll will not be counted or recorded. Voting neutral is not the same as choosing to not participate; please don’t vote neutral if you did not participate in the discussions of the poll.
Each poll has a comment field. Please write a few sentences explaining the rationale for your vote. We recommend drafting your comments in a text editor and then pasting them into the polling system.
Poll results and selected comments will be shared with Library Evolution after the end of the polling period, including attribution of your votes and comments.
If you want to discuss the polls or how you plan on voting, please start an email thread on the Library Evolution mailing list.
If you need to see how you voted, change how you voted, or have any questions or issues about voting, please contact the Library Evolution chair.
