Your workspace: saved collections and comparisons

The workspace holds named collections of EBL records, such as what you take or a set of records you return to for patients, and the pairs you look at side by side. Each saved record shows its letter as it stands today.

A member tool. Everything you save stays in this browser; EBL never receives it.

EBL Pro

The workspace is part of EBL Pro membership. Members sign in to use it.

Any two records can be set side by side on the free comparison page.

How it works

What a collection holds, and what it does not

The records you can add are the graded records the side-by-side comparison offers, with the same letters, copied from the database when the site was last built. When you add a record, the workspace keeps its name, its letter and the date. On every later visit it shows the letter as it stands today; any change to a letter, and the reason for it, is on the record’s own page, in its grade history.

Records stay in the order you added them. Nothing is sorted by letter, and two letters earned on different outcomes are not a ranking: each answers one question about one outcome.

A saved comparison opens the side-by-side view with both records already chosen.

Shared team workspaces and patient packets would keep data on EBL’s side. They are not offered.

What happens to your data

Nothing you save leaves this device. Your collections, notes and comparisons are kept in this browser’s own storage, nothing is sent to EBL or anyone else, and signing in does not copy them to your account. Because EBL holds no copy, a backup file you download is the only way to keep them if you clear this browser or change devices; the same file loads on any device. Deleting them here removes them for good.
