 Google Books you can use the found data using the "fill in" and "replace"

+
+
+Installing via Composer
+=======================
+
+You can use this package in your projects with [Composer](https://getcomposer.org/). Just
+add these lines to your project's `composer.json`:
+
+```
+    "require": {
+        "seblucas/php-epub-meta": "dev-master",
+    },
+    "repositories": [
+        {

+            "url": "https://github.com/mbirth/php-epub-meta"
+        }
+    ]
+```
+
+Since this package requires TbsZip, you might have to add the following lines, too:
+
+```
+    "require": {
+        "Skrol29/tbszip": "dev-master",
+    },
+    "repositories": [

Subject: [PATCH 58/63] added general Date handling

I decided against using DateTime objects since book dates are often not
complete. Eg. 1597 is a valid publishing date, but DateTime would fill
up this date with the current date. Eg. 1597-07-19 which makes not much
sense.
